Constructor & Destructor Documentation

◆ TwoHitFilters() [1/2]

TwoHitFilters ( )

inline

Empty constructor.

For pre-inizialisation only, an object generated this way is useless unless resetValues(a, b) is called at least once

Definition at line 36 of file TwoHitFilters.h.

◆ TwoHitFilters() [2/2]

TwoHitFilters	(	TVector3 &	outerHit,
		TVector3 &	innerHit
	)

inline

Constructor.

needs the first parameter is outer hit, second is inner hit. Parameters in TVector3-format

Definition at line 47 of file TwoHitFilters.h.

Member Function Documentation

◆ resetValues()

void resetValues	(	TVector3 &	outerHit,
		TVector3 &	innerHit
	)

inline

Overrides Constructor-Setup.

Needed if you want to reuse the instance instead of recreating one

Definition at line 56 of file TwoHitFilters.h.
